I My invention relates to improvements in.

hoisting systems tormines,fand more par- ;ticularly in, systems otthe type inwhich the power for elevating: the cage. or other 5: freight carrying member is suppliedbyfwa- I lter f o undat the top of the pit, charged into a receptacle connected with the descending cage and discharged at the bottom of the I r ity of the descending part of the system is at first large and is gradually reduced.

The objectsotthe improvements are, lo first, to providea; system of this type in i i which the water discharged at the bottOmOf the pit is pumpedito the top of theimine for being used over and over again for-supplying power. for elevating the the cage, second,

to provide asystemin'which thefpump for 7 raising the water may be operated at anytime independently ofthe. time of the operation of the hoistingfmachine, so that the power required for operating [the system 20, be stored at any time, for example, at

Above the pit two pulleys 0 and dare mounted. The rope e is secured to the tops and in contact with pulley a3, and the rope e" is, secured to the bottoms of the receptacles g and g". The cages f and fmay be constructed in any known or preferred way.

tain a suitable amount of water. For the purpose of illustration the said receptacles are provided below-the bottom'ofthe cages. But I wish it to be understood that my invention is not limited to this feature. It will therefore be observed from the foregoing "thateach'of the cagesfa'nd f" with its corresponding receptacle gor g" constitute a load carrying member for the elevating or the'loweringof bodies in the mineshaft.

At the bottom of the-pit there is a gallery a h comprising a pool 2' of large capacity communicating with the bottom ofthe pit and adapted to store the water discharged from the descended cages. At the top of the pit and above the ground there is a container: 70' of large capacity adapted to store the water lifted from the pool i by means of a pump Z and through a pipe m. 'The capacity of the containers 2' and k is a mult-iple of that of 10 the receptacles g and 9, so that the hoisting machine can be operated for a considerable large mass, eneeedingfthat' of the rope section 6, its object being to control theveloc'ity of the movement of the receptacles;- VVith 110 the parts shown in the ligrure almost the whole mass of the rope acts on the upper cage f, and the rope tends to pull. the cage downwardly. As the cages apprach the v of the pit.

The operation ot the system is as 'lollows:

When the parts are in the po--rit1on shown in the lia'i'lre the l'tlticpltl ale 5 ol' the cage j" is lilled with water :iroin the container It, and the pulley c is rclca ed il'roiu the brahc n. Now the left hand c: begins its downward movement by the action ol? the gravity of the water and the rope c, whereby acceh crating movement is imparted to the system. Thereby the length of rope c t-llSPt-llltlttl from the cage f is gradually reduced and the length oil rope c acting on the cage 7- is increased.

.l.hcrel."ore the acceu-a'atinn; force acting on the system is reihurcd. When the cages pass the middle of the lift the acceleration of their movement has been reduced to .zero and their velocity is at its maximum.

resistance oi the system and a certain amount Z insuring; movement oil the canes respectively to the top and bottom of the pit. Ordinarily the canes will arrive in their end positions at a certain velocity, and

they are arrested by means of the braltc a.

After the cages have been arresttal the liquid is discharged 'il'Ol'll the receptacle into the pool i whereupon the receptacle 5 is filled with water 'lil'Olll the container 7.: and a new :lreigght is elevated.

The liquid discharged into the container a: is raised to the top oil. the mine by means of the pump Z. rlrn important l cature oi? the invention res es in the fact that the rapacity oi the containers 2' and l: is a large multiple oi that ol the receptacles o and 5 so that the hoisting apparatui-i may be operated tor a considerable length of time without exhausting}; the supply oi liquid from the containers, even iii the pump out o'l operation. llhereby I am enabled to operate the pump only at such periods oil? time when the was consumption of energy by other power consumers is at its minimum, and I can operate the hoisting machine when the electrical or other power plant is out of operation. (lenerally speaking my improved system is adapted to equalize the consumption of power of the electrical power plant, which is of high economical importance.

While in describing the invention reter once has been made to a particular example embodying the same I wish it to he understood that my invention is not limited to the construction shown in the drawing, and that various clnulges may he made in the general arrangement of the apparatus and the construction ol. its parts without departing from the invention.
